No. 15/891,859filed on Feb. 8, 2018, which is a non-provisional of and claims thebenefit of U.S. Provisional Application No. 62/456,616 filed on Feb. 8,2017, and which is also a non-provisional of and claims the benefit ofU.S. Provisional Application No. 62/457,744 filed on Feb. 10, 2017, allof which applications are incorporated herein by this reference in theirentireties.

FIELD OF THE INVENTION

The present invention relates to new and improved sprayers and systemsused for cooling animals, and methods of using the same. The sprayersand systems of the present invention conserve water and energy andprovide adjustability, while minimizing clogging, leaks, down time,monitoring and maintenance in livestock and other animal housingenvironments.

BACKGROUND OF THE INVENTION

There are various industries and operations which house large animals(e.g. dairies, zoos, equine ranches, and the like which may housecattle, horses, swine, or other livestock), and which are based inlocalities having hot outdoor climates, especially during the summer.Such operations may rely on an animal spraying system which cools theanimals during hotter hours of the day by sprinkling the animals withwater. However, water usage at such operations may come at a premium asaccess to water lessens and water costs increase during periods of highdemand, and water availability may be restricted due to drought-likeconditions and mandated rationing. Such operations would benefit fromautomated animal spraying systems that provide a predictable demand forwater, thereby improving system water pressure, and conserving water andenergy.

Conventional water spraying systems rely on solenoid or butterfly valveactuators to control water flow. A typical solenoid actuator is amagnetically controlled binary valve wherein a valve is eithercompletely open or completely closed. The solenoid is operated bysending electric current through a coil to magnetize a piston, whichthen pushes against a spring to hold the valve open. Because the springis always pushing against the piston, the valve requires constantelectrical current to remain open. This setup is not ideal for batteryoperated sprayer systems, as it uses energy during the entire sprayingsession. Further, the volume of water allowed through the valve is notadjustable, as the valve only has a full on or full off position. Thus,other apparatus would be required to optimize the volume of water usedfor spraying and/or animal cooling.

A typical butterfly valve operates by sliding a flat metal seal along asurface. The seal and the surface each have a circular hole, and whenthe holes are aligned water is allowed through. Due to the irregularshape of the opening created as the circular hole in the seal slidesinto position over the circular shape of the surface, the flow rate ofwater through a butterfly valve is not linearly proportional to themovement of the seal. Thus, making slight adjustments to the flow ratethrough a butterfly valve is not easy and may require personalmonitoring. Further, due to the shape of the pathway created by abutterfly valve wherein turbulence is created by water pushing againstand flowing past a flat metal sheet, a butterfly valve is moresusceptible to developing leaks and accumulating debris on the outersurface of the seal. This makes butterfly valves unsuitable for use industy, dirty environments such as dairy farms or zoos.

There is therefore a need for automatic animal water spraying systemshaving adjustable valves that are suitable for dusty dirty conditions,with actuators that do not require constant electric current to holdvalves open during a spraying session, and which control the timing ofspraying sessions, so as to conserve water and energy and provideadjustability, while minimizing clogging, leaks, down time, monitoringand maintenance. Operations engaged in housing large animals in hotenvironments subject to droughts and water rationing would be aided byanimal cooling systems which reduce water use and maintenance costswhile providing consistent water pressure and reliability.

SUMMARY OF THE INVENTION

The present invention provides animal spraying systems and relatedmethods for use in industries and activities such as cattle ranches,dairies, swine or equine ranches, zoos, and the like, to provideautomatic, low maintenance, water conserving and energy efficientspraying of animals to cool the animals during hot weather. Embodimentsof the animal spraying systems and methods of the present invention mayinclude a unitary device for attachment to an existing main water line,the device comprising a valve with a valve body and a valve stem whichmay be self-cleaning, a motor for turning the valve stem, a pressureswitch for recognizing a threshold water pressure (e.g., 5 psi), asensor for detecting an animal, a power source, an optional voltageindicator for showing that the power source has dropped below apredetermined voltage (e.g. below 7.4 volts), and a microcontroller for(1) receiving electric current from a first circuit via the pressureswitch, (2) sending a signal to a first transistor switch to close asecond circuit, (3) sending a signal to a second transistor switch toactivate the sensor, (4) receiving a positive detection signal from thesensor, (5) controlling the motor, and optionally (6) activating the lowvoltage indicator.

Embodiments of the present invention may also include a housing tosupport and protect the valve, pressure switch, motor, sensor, powersource, microcontroller, first transistor switch, second transistorswitch, and voltage indicator. The housing may be made of a rigidmaterial such as metal or plastic, having a bottom with a shape that iscomplementary to the shape of a water pipe, such that the housing may besecurely installed on, and tap into, the water pipe. The housing may beinstalled on the water pipe by tapping said water pipe and creating awatertight seal between the water pipe and an inlet of the valve body.The watertight seal may comprise a weld, a gasket, a threadedconnection, a pipe adhesive (e.g. pipe glue), or other suitable sealingmaterial or combination(s) thereof. The water pipe may then providewater pressure to the inlet.

Water pressure in the main water pipe is controlled separately from thepresent invention, and a plurality of the devices of the presentinvention may be placed on such a pipe. The main water pipe may becontrolled by a separate pump with or without a timer, such that waterpressure is provided at whatever times are desired. For example, andwithout limitation, water may be continuously provided in the main pipein extremely hot and dry climates; in other climates, water may only beprovided during a predetermined time of day (e.g. during the hottesttime of the day), and/or only for predetermined periods of time (e.g.,for 15 minutes, or 30 minutes, or 1 hour, etc.), or at pre-determinedintervals (e.g., 15 minutes every hour; 15 minutes every 2 hours; 15minutes every 4 hours; etc), thus creating one or more spraying periods.There may be one spraying period in a day, or a plurality of sprayingperiods in a day; and the spraying period(s) may last for only a fewminutes or up to several hours. Utilization of the spraying period mayreduce wear on the animal spraying device, reduce the chance for leaks,and help conserve water. As discussed more fully below, it is to beappreciated that embodiments of the present invention are not activateduntil there is water pressure in the main pipe, according to whateverschedule has been set for pressurizing that pipe.

Embodiments of the valve body may have an inlet chamber connected to theinlet, the inlet chamber housing a pressure activated piston which, whenthe water pipe provides the threshold water pressure to the inlet duringthe spraying period, activates the pressure switch. The pressure switchmay then close a first circuit between the power source and amicrocontroller, allowing the microcontroller to enter a startup modewherein the microcontroller is operable to: (1) boot up; (2) signal afirst transistor switch to close a second circuit; (3) signal the motorto close the valve; and (4) signal a second transistor switch toactivate the sensor. It is to be appreciated that until the pressureswitch is activated by the presence of the threshold water pressure inthe water pipe, there is no drain on battery power.

After completing startup mode, embodiments of the animal sprayer devicemay enter a spraying mode, wherein it checks for the presence of ananimal. The sensor may detect an animal in the target area of thespraying system and send a positive detection signal to themicrocontroller, causing the microcontroller to activate the motor,opening the valve and allowing water to spray the animal. The sensor maythen continue to monitor the target area, and when the animal leaves thetarget area the sensor may send a negative detection signal to themicrocontroller. The microcontroller may then cause the motor to closethe valve, conserving water when an animal is not present to be sprayed.The sensor may also have the effect of deterring pests by emittingultrasonic waves which are offensive to avian or rodent pests, causingthe pests to leave the vicinity of the animal sprayer. It is to beappreciated that in sine embodiments of the invention, one or moreproximity sensors may be employed. It is also to be appreciated that insome embodiments of the invention, the proximity sensor(s) may be set soas to only detect large animals (such as livestock) as opposed to smallanimals (such as rodents).

In embodiments of the invention, an inlet chamber of the valve body mayhouse a spring which pushes back against the pressure activated piston,such that when the spraying period ends (when water in the pipe nolonger provides the threshold water pressure to the inlet, e.g. when thepump is shut off), the piston no longer engages the pressure switch. Thepressure switch may then open the first circuit between the power sourceand the microcontroller.

At this point, in embodiments of the invention, the microcontroller, themotor, and the sensor may all still receive power via the secondcircuit. In such embodiments, the microcontroller may continuouslymonitor the voltage coming from the first circuit, and enter a shut-downmode upon the first circuit being opened. In shut-down mode, themicrocontroller may be operable to: (1) signal the motor to close thevalve; and (2) signal the first transistor switch to open the secondcircuit, shutting off power to the microcontroller. Together, thesefunctions may prevent residual water use, assist in quickly bringing upgood water pressure from the water pipe at the next spraying period, andconserve power from the power source between spraying periods.

Embodiments of the valve body may also include an outlet chamber, theoutlet chamber having an inner surface with threading which iscomplementary to threading on an outer surface of the valve stem. Thevalve stem may have a gear at its base complementary to a gear of themotor, such that as the motor turns, the valve stem is threaded into orout of the outlet chamber of the valve body. The valve stem may alsohave a substantially hemispherical plug at its tip with an outerdiameter which is complementary to a tapered end of a sealing passagebetween the inlet chamber and the outlet chamber of the valve body.Thus, when the valve stem is threaded into the outlet chamber, the plugengages the sealing passage and the valve is closed. Conversely, whenthe valve stem is threaded out of the outlet chamber, water is allowedto pass from the inlet chamber through the sealing passage and aroundthe plug in a symmetrical manner. The valve may thus provide a linearincrease in water volume as the valve stem is threaded out of the valvebody. Further, the valve may be self-cleaning, as the symmetrical waterflow through the sealing passage and around the plug prevents buildup ofdebris or sediment in the valve, decreasing the need for maintenance andthe likelihood of developing a leak.

In embodiments of the invention, the outlet may also have asubstantially cylindrical shape with an inner surface, the inner surfacehaving threading which is complementary to a threading of a connector ofa standard nozzle or service line.

The power source may comprise a battery, although solar or otherremotely available power sources may be used. The optional voltageindicator may comprise a light emitting diode (LED) indicator, whereinthe LED indicator begins flashing once power coming from the batterydrops below the predetermined voltage (e.g., 7.4 volts). Otherlow-voltage indicators may also be used, including without limitationaudio (which emits sound chirps at low voltage), wired or wirelesscommunications, etc. Use of a voltage indicator is preferred, since atypical microcontroller may require a threshold voltage (e.g., 7.2volts) to function, and may cease to operate when voltage from the powersource drops below the threshold voltage.

In embodiments having the voltage indicator, the microcontroller maycontinuously monitor the voltage level coming from the battery via thefirst circuit (the first circuit voltage), and when the power leveldrops below a predetermined voltage (e.g., 7.4 volts), themicrocontroller may enter a low power mode and activate the voltageindicator to show that the battery is low. In some embodiments, theanimal sprayer device may be capable of operating in low power modeuntil the first circuit voltage drops below a minimum voltage (e.g. 4.5volts).

In some embodiments, while in low power mode the animal sprayer devicemay not enter shut-down mode at the end of a spraying period. Instead,the microcontroller may be operable to send a signal to a secondtransistor switch to cut off power to the sensor. The second circuit maythus continue to power the voltage indicator to indicate a low powerlevel of the power source, but not power the sensor, conserving batterypower.

In embodiments comprising the low power mode, the microcontroller may beprogrammed to close the valve at the end of a spraying period in orderto conserve water, or the microcontroller may be programmed to leave thevalve open at the end of a spraying period in order to conserve power.In some embodiments, the animal sprayer device may be operable to exitthe low power mode upon the first circuit voltage rising above thethreshold voltage.

It is to be appreciated that most embodiments of the present inventionare stand-alone units that can be used with any water line, as long asthat line provides sufficient pressure. However, in some embodiments anauxiliary or exterior power source may be available, such as, forexample, an A/C line from a utility company, or a D/C line from a solarpower source. In such cases, the external power source can be used topower embodiments of the invention, instead of the battery, and/or thebattery may become a backup power supply if the exterior power sourcefails. In such embodiments, much longer run times are available sincethere is no depletion of the battery.

In some embodiments, the present invention is directed to an animalspraying device comprising a valve with a valve body and a valve stemfor controlling a flow of water through said valve; a power source; amotor for turning said valve stem; a pressure switch for recognizing athreshold water pressure (e.g., 5 psi) from a water pipe; a sensor fordetecting an animal within a target area; a voltage indicator forindicating a low power level; and a microcontroller for (1) receivingelectric current from a first circuit via the pressure switch, (2)sending a signal to a first transistor switch to close a second circuit,(3) sending a signal to a second transistor switch to power the sensor,(4) receiving a positive detection signal from the sensor, (5)controlling the motor, and (6) activating the low voltage indicator.

In some embodiments, the present invention may be installed on a waterpipe by tapping the water pipe and creating a watertight seal betweenthe water pipe and an inlet of the valve body. The watertight seal maycomprise a weld, a gasket, a threaded connection, or a pipe adhesive(e.g. pipe glue), or a combination thereof.

In some embodiments, and without limiting the invention, a valve bodymay comprise said inlet, an inlet chamber, a seal passage, an outletchamber, and an outlet. In some embodiments, the inlet may comprise aninlet opening and an inlet passage, the inlet passage allowing fluidcommunication between said inlet opening and said inlet chamber. In someembodiments, the inlet opening may be in fluid communication with awater pipe via a watertight seal, with the water pipe providing waterpressure to said inlet during a spraying period. In some embodiments,the inlet chamber may comprise a substantially cylindrical shape with aproximal end and a distal end. In some embodiments, the inlet passageand the seal passage may be located at the proximal end, and thepressure switch may be located at the distal end.

In some embodiments, a valve body may comprise an inlet with an inletopening, and an outlet with an outlet opening. In some embodiments, theinlet opening may allow fluid communication between a water pipe and avalve. In some embodiments, the outlet opening may comprise outletthreading, the outlet threading comprising a shape which iscomplementary to a threading of a standard nozzle or service line, suchthat the valve may be connected in a watertight manner to the standardnozzle or service line, the standard nozzle or service line directingthe flow of water to a target area. In some embodiments, the valve maythus provide fluid communication between the water pipe and the targetarea.

In some embodiments, an inlet chamber may house a pressure activatedpiston and a spring. In some embodiments, the spring may be locatedbetween a distal end and a pressure activated piston, wherein the springprovides physical resistance against contact between the pressureactivated piston and a pressure switch. In some embodiments, a thresholdwater pressure from a water pipe may overcome physical resistance fromthe spring, causing the pressure activated piston to contact thepressure switch, closing a first circuit between the power source andthe microcontroller.

In some embodiments, an outlet chamber may comprise a substantiallycylindrical shape with an inner surface, a proximal end, and a distalend. In some embodiments, a seal passage and an outlet are located atthe proximal end. In some embodiments, the outlet chamber may comprise achamber threading on the inner surface, the chamber threading or borebeing located at the distal end.

In some embodiments, the seal passage may comprise a substantiallycylindrical shape with a tapered outlet end, the seal passage providingfluid communication between an inlet chamber and an outlet chamber.

In some embodiments, a valve stem may comprise a first end, a secondend, and a shaft. In some embodiments, the first end may comprise ahead, a neck, and a shoulder, the head and the neck creating a shapecomplementary to an inner cavity of a plug, wherein the plug fitssecurely onto the first end. In some embodiments, the plug may comprisethe inner cavity and a substantially hemispherical tip. In someembodiments, the substantially hemispherical tip may comprise a shapecomplementary to a shape of the tapered outlet end of the seal passage,such that when the hemispherical tip contacts the tapered outlet end, awatertight seal is created between the seal passage and the outletchamber.

In some embodiments, an O-ring may be installed on the shoulder of thevalve stem, the O-ring having an inner diameter and an outer diameter.In some embodiments, the inner diameter of the O-ring may becomplementary to an outer diameter of the shoulder, and the outerdiameter of the O-ring may be complementary to an inner diameter of theoutlet chamber, such that a watertight seal is created between theoutlet chamber and the valve stem.

In some embodiments, the shaft of the valve stem may comprise asubstantially cylindrical shape with an outer surface, the outer surfacecomprising a stem threading. In some embodiments, the stem threading maycomprise a shape complementary to the chamber threading, such that thevalve stem may be threaded into the outlet chamber. In some embodiments,the second end of the valve stem may comprise a stem gear, the stem gearcomprising a shape complementary to a shape of a motor gear, with themotor gear being connected to the motor.

In some embodiments, the stem gear may be in contact with the motorgear, such that when the motor turns the motor gear a in firstdirection, the valve stem may be threaded into the outlet chamber,moving along a central axis of the valve stem, and when the motor turnsthe motor gear in a second direction, the valve stem may be threaded outof the outlet chamber, moving back along the central axis of the valvestem (collectively, an axial movement of the valve stem). In someembodiments, when the valve stem is threaded into the outlet chamber, aplug may come into contact with a seal passage, closing the valve, andwhen the valve stem is threaded out of the outlet chamber, the plug maydisengage from the seal passage, opening the valve. In some embodiments,the flow rate of water passing through the valve may be linearlyproportional to an axial movement of the valve stem.

In some embodiments, the motor gear may have an outer diametersubstantially greater than an outer diameter of the stem gear, creatinga reduction gear transmission between the motor and the valve stem, thuspreventing an axial movement of the valve stem during the sprayingperiod, conserving power from the power source.

In some embodiments, an outlet of the valve body may comprise an outletopening and an outlet passage, the outlet passage allowing fluidcommunication between the outlet chamber and the outlet opening. In someembodiments, the outlet opening may comprise a cup shape with an innercylindrical surface. In some embodiments, the inner cylindrical surfacemay comprise an outlet threading, the outlet threading comprising ashape complementary to a threading of a connector of a standard nozzleor service line.

In some embodiments, the sensor may comprise an ultrasonic sensor and asensor horn. In other embodiments, the sensor may comprise at least oneof a passive infrared sensor, a microwave sensor, an area reflectivetype sensor, a vibration sensor, or a dual technology sensor. In someembodiments, the ultrasonic sensor may be operable to send out pulses ofultrasonic waves and measure the reflection of an object within apredetermined range of the sensor (e.g., between 6 and 15 feet), thepredetermined range representing a target area of the animal sprayerdevice. In some embodiments, the sensor may be operable to detect onlyanimals meeting a threshold size (e.g., greater than 100 lbs., or havinga surface area of more than 12 sq. in.), the threshold size preventingthe sensor from detecting smaller animals such as dogs, cats, birds, orrodents.

In some embodiments, the sensor may be provided in a horn that maycomprise a substantially L shaped passage with a first end and a secondend. In some embodiments, the ultrasonic sensor may be located at thefirst end, with the second end being open and directed toward the targetarea. In some embodiments, the sensor may comprise a screen, the screencovering the second end of the sensor horn and protecting the ultrasonicsensor from water and debris. In some embodiments, the sensor maycomprise a plurality of ultrasonic sensors and a plurality of sensorhorns. In some embodiments, each sensor horn in the plurality of sensorhorns may be directed to the target area. In other embodiments, theplurality of sensor horns may comprise a first sensor horn and a secondsensor horn, the first sensor horn being directed to a first targetarea, and the second sensor horn being directed to a second target area.It is to be appreciated that one, two, three or more sensor(s) andassociated horn(s) may be provided in different embodiments of theinvention.

In some embodiments, the sensor may ping a target area multiple timesper second (e.g., 20 times per second), and receive a positive detectionif an animal moves into the target area. In some embodiments, the sensormay require multiple consecutive positive detections (e.g., sixconsecutive positive detections) before recording a valid positivedetection. In some embodiments, upon recording a valid positivedetection, the sensor may transmit a positive detection signal to themicrocontroller, causing the microcontroller to activate the motor andopen the valve, spraying the animal.

In some embodiments, upon transmitting a positive detection signal tothe microcontroller, the sensor may cease pinging the target area, andthe valve may remain open for the duration of the spraying period (i.e.,as long as there is water pressure in the main pipe). In otherembodiments, the valve may remain open for a predetermined time (e.g.,one minute, ten minutes, fifteen minutes, or any other suitable timeinterval) before the microcontroller activates the motor to close thevalve, thereby ending a spraying session. In some embodiments, theanimal spraying device may provide zero spraying sessions, or onespraying session, or a plurality of spraying sessions, during a sprayingperiod.

In yet other embodiments, the sensor may continue pinging a target area,and upon receiving multiple consecutive negative detections (e.g. 50consecutive negative detections) the sensor may record a valid negativedetection and send a negative detection signal to the microcontroller,causing the microcontroller to activate the motor and close the valve.In some embodiments, the sensor may then continue pinging the targetarea for the duration of a spraying period, allowing for a second validpositive detection, thus allowing for multiple animals to be sprayedduring one spraying period.

In some embodiments, upon initially receiving power from the firstcircuit, the microcontroller may automatically transmit a signal to afirst transistor switch to close a second circuit between the powersource and the microcontroller. Thus, if the spraying period ends andthe pressure switch opens the first circuit while the valve is open, themicrocontroller may continue receiving power from the second circuit inorder to cause the motor to close the valve. After causing the motor toclose the valve, the microcontroller may then signal the firsttransistor switch to open the second circuit, cutting off battery useentirely.

In some embodiments, if the animal sprayer device is in low power modewhen the spraying period ends, the microcontroller may not signal thefirst transistor switch open the second circuit, so that the voltageindicator may continue to receive power in order to signal a low powerlevel in between spraying periods. In some embodiments, if the animalsprayer device is in low power mode, the microcontroller may not closethe valve when the spraying period ends, thus conserving power andensuring that the valve is in an open position for the next sprayingperiod. In other embodiments, the microcontroller may close the valve atthe end of the spraying period irrespective of whether the animalsprayer device is in low power mode.

In some embodiments, the pulses of ultrasonic waves transmitted by thesensor may also have the effect of deterring pests. The ultrasonic wavesmay be offensive to avian and rodent pests within a deterrent area(e.g., within 1 to 48 inches, or up to several feet) around the animalsprayer device, causing the pests to leave the deterrent area and thusleave the vicinity of the animal sprayer. The sensor may thus preventdamage to the animal sprayer caused by physical contact by the pests,and prevent pest droppings in the vicinity of the animal sprayer.

In some embodiments, the sensor may receive power via either the firstcircuit or the second circuit, via a second transistor switch. In suchembodiments, the second transistor switch may be operable to transferpower to the sensor upon receiving an activation signal from themicrocontroller, or a cut off power to the sensor upon receiving adeactivation signal from the microcontroller. In some embodiments, themicrocontroller may automatically send the activation signal to thesecond transistor switch upon the microcontroller entering startup mode.In some embodiments, the microcontroller may send the deactivationsignal to the second transistor switch upon entering low power mode.

In some embodiments, the power source may comprise a battery. In someembodiments, the battery may comprise a plurality of commerciallyavailable batteries (e.g., AAA, AA, C, or D batteries, etc.). In otherembodiments, the battery may comprise a removable and rechargeablesystem battery. In some embodiments, the power source may be inelectronic communication with the pressure switch, the pressure switchbeing in electronic communication with the microcontroller. In someembodiments, the pressure switch may be capable of opening or closing afirst circuit between the power source and the microcontroller. In someembodiments, the pressure switch may open a first circuit when thepressure activated piston is not in contact with the pressure switch(i.e., detecting the absence of water pressure, thereby preventing thevalve from operating), and close the first circuit when the pressureactivated piston is in contact with the pressure switch (i.e. detectingthe presence of the threshold water pressure, such that the valve may beoperable for spraying if an animal which comes into the target area).

In some embodiments, the battery may further be in electroniccommunication with a first transistor switch, the first transistorswitch being in electronic communication with the microcontroller. Insome embodiments, the first transistor switch may be capable of closinga second circuit between the power source and the microcontroller. Insome embodiments, the first transistor switch may close the secondcircuit upon receiving a signal from the microcontroller, thus bypassingthe first circuit. In some embodiments, upon receiving power via thefirst circuit, the microcontroller may automatically signal the firsttransistor switch, opening the second circuit.

In some embodiments, the microcontroller may continuously monitor thevoltage coming from the power source via the first circuit, and enter alow power mode upon the first circuit voltage dropping below apredetermined voltage. In some embodiments, upon entering low power modethe microcontroller may not signal the first transistor switch to openthe second circuit at the end of a spraying period, thus keeping thesecond circuit closed for the purpose of powering a voltage indicator.In some embodiments, in low power mode and at the end of a sprayingperiod, the microcontroller may signal a second transistor switch toshut off power to the sensor, conserving battery power.

In some embodiments, the voltage indicator may comprise a light emittingdiode (LED) indicator and be operable to receive power from themicrocontroller. In some embodiments, upon receiving a signal from themicrocontroller, the LED indicator may be operable to pulse at a regularinterval (e.g. one 0.5 second pulse every five seconds). In someembodiments, the LED indicator may continue to pulse at regularintervals until the microcontroller exits low power mode and signals theLED indicator to shut off In some embodiments, the animal sprayer devicemay be capable of operating in low power mode until the first circuitvoltage drops below a minimum voltage (e.g. 4.5 volts).

In some embodiments, the microcontroller may comprise a centralprocessing unit (CPU), the CPU being in electronic communication with apressure switch, a first transistor switch, a second transistor switch,a motor, a sensor, and a voltage indicator. In some embodiments, themicrocontroller may be operable to receive power from a power source viaa first circuit and a second circuit, the first circuit being opened orclosed by the pressure switch, and the second circuit being opened orclosed by the first transistor switch. In some embodiments, the pressureswitch may close the first circuit upon the water pipe delivering waterpressure to the valve during a spraying period, and open the firstcircuit upon the cessation of said threshold water pressure from thewater pipe at the end of the spraying period.

In some embodiments, the microcontroller may be operable to: (1) receivepower from the power source via the closing of the first circuit; (2)signal the first transistor switch to close the second circuit; (3)automatically transmit a negative detection signal to the motor toinitially close the valve and conserve water; (4) send a signal to thesecond transistor switch to activate the sensor; (5) receive a positivedetection signal from the sensor upon an animal entering the targetarea; (6) transmit a positive detection signal to the motor to open thevalve; (7) receive a negative detection signal from the sensor upon theanimal leaving the target area; (8) transmit a negative detection signalto the motor to close the valve and conserve water; (9) monitor thefirst circuit voltage; (10) upon the first circuit voltage droppingbelow a predetermined voltage, enter low power mode and activate thevoltage indicator, causing the voltage indicator to pulse at a regularinterval; (11) upon the first circuit being opened while not in lowpower mode, close the valve and signal the first transistor switch toopen the second circuit; (12) upon the first circuit being opened whilein low power mode, either close the valve to conserve water or leave thevalve open to conserve power, and signal the second transistor switch tocut off power to the sensor, conserving battery power; and (13) upon thefirst circuit voltage rising above the predetermined voltage, exit lowpower mode.

Some embodiments of the invention may comprise a housing. In suchembodiments, the housing may comprise a rigid material (e.g., plastic ormetal) and may comprise openings for an inlet, an outlet, a sensor, anda voltage indicator. In some embodiments, the housing may furthercomprise a bottom surface with at least one attachment tab, and a pipegasket, the pipe gasket comprising an upper surface, a rounded firstend, and a rounded second end. In some embodiments, the upper surfacemay comprise a substantially flat shape, a passage for the inlet, and atleast one attachment slot for attaching to the at least one attachmenttab. In some embodiments, the rounded first end and the rounded secondend may each comprise a shape which is complementary to an outer surfaceof the water pipe.

Additional aspects and objects of the invention will be apparent fromthe detailed descriptions and the claims herein.

In some embodiments, said animal sprayer device 100may comprise a valve 110 with a valve body 111 and a valve stem 130 forcontrolling a flow of water through said valve 110, a motor 150 forturning said valve stem 130, a pressure switch 160 for recognizing athreshold water pressure (e.g., 5 psi) from a water pipe, a proximitysensor 180 for detecting the presence of an animal within a target area,a power source 171, a voltage indicator 170 for indicating a power levelof said power source 171 below a predetermined voltage, and amicrocontroller 161 for: (1) receiving power from said power source 171via said pressure switch 160, (2) sending a signal to a first transistorswitch 164 to close a second circuit 173, bypassing said first circuit172; (3) sending a signal to a second transistor switch 165 toactivating said sensor 180, (4) receiving a positive detection signalfrom said sensor 180, (5) controlling said motor 150, and optionally,(6) activating said voltage indicator 170.

In some embodiments, said motor 150 may comprise a motor gear 151 andsaid valve stem 130 may comprise a stem gear 136, said motor gear 151comprising a shape which is complementary to a shape of said stem gear136. In some embodiments, said motor gear 151 may be in contact withsaid stem gear 136, such that when said motor 150 turns, said valve stem130 also turns.

In some embodiments, said valve body 111 may comprise an inlet 112 withan inlet opening 113, and an outlet 122 with an outlet opening 123. Insome embodiments, said inlet 113 opening may allow fluid communicationbetween said water pipe and said valve 110. In some embodiments, saidoutlet opening 123 may comprise outlet threading 125, said outletthreading 125 comprising a shape which is complementary to a threadingof a standard nozzle or service line, such that said valve 110 may beconnected in a watertight manner to said standard nozzle or serviceline, said standard nozzle or service line directing said flow of waterto said target area. In some embodiments, said valve 110 may thusprovide fluid communication between said water pipe and said targetarea.

In some embodiments, said sensor 180 may comprise an ultrasonic sensor181 and a sensor horn 182. In some embodiments, said ultrasonic sensor181 may be operable to send out pulses of ultrasonic waves and measurethe reflection of an object within a predetermined range of said sensor180 (e.g., between 6 and 15 feet), said predetermined range representingsaid target area. In some embodiments, said sensor 180 may be operableto detect only animals meeting a threshold size (e.g., greater than 100lbs. or greater than 12 sq. in.), said threshold size preventing saidsensor from detecting smaller animals such as dogs, cats, birds, orrodents.

In some embodiments, the pulses of ultrasonic waves transmitted by saidsensor 180 may also have the effect of deterring pests. The ultrasonicwaves may be offensive to avian and rodent pests within a deterrent area(e.g., within 1 to 48 inches, or up to several feet) around the animalsprayer device 100, causing the pests to leave said deterrent area andthus leave the vicinity of said animal sprayer device 100. Said sensor180 may thus prevent damage to said animal sprayer device 100 caused byphysical contact by the pests, and prevent pest droppings in thevicinity of said animal sprayer device 100.

In some embodiments, said sensor horn 182 may comprise a substantially Lshaped passage with a first end 183 and a second end 184, said L shapedpassage providing protection for and directing ultrasonic waves to saidultrasonic sensor 181. In some embodiments, said ultrasonic sensor maybe located at said first end 183, and said second end 184 may be openand directed toward said target area through one or more openings 186 inhousing 101. In some embodiments, said sensor 180 may comprise a screen185 (see FIG. 7A), said screen 185 covering said second end 184 andprotecting said ultrasonic sensor 181 from water and debris. In someembodiments, said sensor 180 may comprise a plurality of ultrasonicsensors and a plurality of sensor horns. In some embodiments, eachsensor horn in said plurality of sensor horns may be directed to saidtarget area. In some embodiments, horn(s) 182 may be eliminated suchthat the sensor(s) 180 may be mounted flush to the housing 101.

An alternative embodiment illustrated in FIGS. 9-12 shows the use of asingle sensor 180. In such embodiments, an embodiment of housing 101having a single sensor opening 186 may be employed. Or, as shown inFIGS. 9-12, any extra openings 186 in housing 101 may be plugged usingcaps 187. In the exemplary embodiment of FIGS. 9-12, it is seen thatsensor 180 may be mounted generally flush with the external surface ofhousing 101. Sensor 180 is in electronic communication withmicroprocessor 161. FIG. 13 shows detail of an embodiment of amicroprocessor illustrating the circuitry which controls the sensor(180), motor (150), and the battery/button/and voltage indicator (170).

In some embodiments, said sensor 180 may ping said target area multipletimes per second (e.g., 20 times per second), and receive a positivedetection if an animal moves into said target area. In some embodiments,said sensor 180 may require multiple consecutive positive detections(e.g., six consecutive positive detections) before recording a validpositive detection. In some embodiments, upon recording a valid positivedetection, said sensor 180 may transmit a positive detection signal tosaid microcontroller 161, causing said microcontroller 161 to activatesaid motor 150, opening said valve 110, and spraying said animal.

In some embodiments, upon transmitting said positive detection signal tosaid microcontroller 161, said sensor 180 may cease pinging the targetarea, and said valve 110 may remain open for the duration of saidspraying period. In other embodiments, said valve 110 may remain openfor a predetermined spraying time (e.g. one minute, ten minutes, fifteenminutes, or any other suitable time period) before said microcontroller161 activates said motor 150 to close said valve 110, thereby creating aspraying session. In some embodiments, said animal spraying device 100may thus provide zero spraying sessions, or one spraying session, or aplurality of spraying sessions, during said spraying period.

In yet other embodiments, said sensor 180 may continue pinging saidtarget area and upon receiving multiple consecutive negative detections(e.g. 50 consecutive negative detections) said sensor 180 may record avalid negative detection and send a negative detection signal to saidmicrocontroller 161, causing said microcontroller 161 to activate saidmotor 150 and close said valve 110. In some embodiments, said sensor 180may then continue pinging said target area for the duration of saidspraying period, allowing for a second valid positive detection, thusallowing for multiple animals to be sprayed during said spraying period.

In some embodiments, said sensor 180 may receive power via either saidfirst circuit 172 or said second circuit 173, via a second transistorswitch 165. In such embodiments, said second transistor switch 165 maybe operable to transfer power to said sensor 180 upon receiving anactivation signal from said microcontroller 161, or a cut off power tosaid sensor 180 upon receiving a deactivation signal from saidmicrocontroller 161. In some embodiments, said microcontroller 161 mayautomatically send said activation signal to said second transistorswitch 165 upon said microcontroller 161 entering startup mode. In someembodiments, said microcontroller 161 may send said deactivation signalto said second transistor switch 165 upon entering low power mode.

In some embodiments, said power source 171 may comprise a battery. Insome embodiments, said battery may comprise a plurality of commerciallyavailable batteries (e.g., AAA, AA, C, or D batteries, etc.). In someembodiments, said power source 171 may be in electronic communicationwith said pressure switch 160, said pressure switch 160 being inelectronic communication with said microcontroller 161.

In some embodiments, said voltage indicator 170 may comprise a lightemitting diode (LED) indicator and be operable to receive an activationsignal from said microcontroller 161. In some embodiments, uponreceiving said activation signal from said microcontroller 161, said LEDindicator may be operable to pulse at a regular interval (e.g. one 0.5second pulse every five seconds). In some embodiments, said LEDindicator may continue to pulse at said regular interval until saidmicrocontroller 161 sends a deactivation signal to said LED indicator.

Without limiting the invention, FIGS. 4 and 5 show an exemplaryembodiment of an animal sprayer device 100 according to an embodiment ofthe present invention. In some embodiments, said animal sprayer devicemay comprise a valve 110 with a valve body 111 and a valve stem 130, anda motor 150 with a motor gear 151.

In some embodiments, saidinlet 112 may comprise an inlet opening 113 and an inlet passage 114,said inlet passage 114 allowing fluid communication between said inletopening 113 and said inlet chamber 115. In some embodiments, said inletopening 113 may be in fluid communication with said water pipe via awatertight seal, said water pipe providing a threshold water pressure tosaid inlet 112 during a spraying period.

In some embodiments, said inlet chamber 115 may comprise a substantiallycylindrical shape with a proximal end 115 a and a distal end 115 b. Insome embodiments, said inlet passage 114 and said seal passage 118 maybe located at said proximal end 115 a, and said pressure switch 160 maybe located at said distal end 115 b.

In some embodiments, said inlet chamber 115 may house a pressureactivated piston 116 and a spring 117. In some embodiments, said spring117 may be located between said distal end 115 b and said pressureactivated piston 116, wherein said spring 117 provides physicalresistance against contact between said pressure activated piston 116and said pressure switch 160. In some embodiments, said threshold waterpressure from said water pipe may overcome said physical resistance fromsaid spring 117, causing said pressure activated piston 116 to contactsaid pressure switch 160 and close a first circuit 172 between saidpower source 171 and said microcontroller 161.

In some embodiments, said outlet chamber 120 may comprise asubstantially cylindrical shape with a proximal end 120 a, and a distalend 120 b. In some embodiments, said seal passage 118 and said outlet122 may be located at said proximal end 120 a. In some embodiments, saidoutlet chamber or bore 120 may comprise a chamber threading 121, saidchamber threading 121 being located at said distal end of said bore 120b.

In some embodiments, said seal passage 118 may comprise a substantiallycylindrical shape with a tapered outlet end 119, said seal passage 118providing fluid communication between said inlet chamber 115 and saidoutlet chamber 120.

In some embodiments, said valve stem 130 may comprise a first end 130 a,a second end 130 b, and a shaft 134. In some embodiments, said first end130 a may comprise a head 131, a neck 132, and a shoulder 133, said head131 and said neck 132 creating a shape complementary to an inner cavity137 a of a plug 137, wherein said plug 137 fits securely onto said firstend 130 a. In some embodiments, said plug 137 may comprise asubstantially hemispherical tip 137 b, said substantially hemisphericaltip 137 b comprising a shape complementary to a shape of said taperedoutlet end 119 of said seal passage 118, such that when saidsubstantially hemispherical tip 137 a contacts said tapered outlet end119, a watertight seal is created between said seal passage 118 and saidoutlet chamber 120.

In some embodiments, an O-ring 138 may be provided on said shoulder 133,said O-ring 138 having an inner diameter and an outer diameter. In someembodiments, said inner diameter of said O-ring 138 may be complementaryto an outer diameter of said shoulder 133, and said outer diameter ofsaid O-ring 138 may be complementary to an inner diameter of proximalend 120 a of said outlet chamber 120, such that a watertight seal iscreated between said proximal end 120 a and said valve stem 130.

In some embodiments, said shaft 134 may comprise a substantiallycylindrical shape with stem threading 135. In some embodiments, saidstem threading 135 may comprise a shape complementary to said chamberthreading 121, such that said valve stem 130 may be threaded into saidoutlet chamber 120. In some embodiments, said second end 130 b maycomprise a stem gear 136, said stem gear 136 comprising a shapecomplementary to a shape of said motor gear 151.

In some embodiments, said stem gear 136 may be in contact with saidmotor gear 151, such that when said motor 150 turns said motor gear 151in first direction, said valve stem 130 may be threaded into said outletchamber 120, moving along central axis of said valve stem 130, and whensaid motor 150 turns said motor gear 151 in a second direction, saidvalve stem 130 may be threaded out of said outlet chamber 120, movingback along said central axis of said valve stem 130 (collectively, anaxial movement).

In some embodiments, when said valve stem 130 is threaded into saidoutlet chamber 120, said plug 137 may come into contact with said sealpassage 118, closing said valve 110, and when said valve stem 130 isthreaded out of said outlet chamber 120, said plug 137 may disengagefrom said seal passage 118, opening said valve 110 and allowing saidflow of water to pass from said inlet chamber 115 through said sealingpassage 118 and around said plug 137 in a symmetrical manner beforeexiting said outlet chamber 120 through said outlet passage 124 and outsaid outlet 122 via said outlet opening 123. In some embodiments, therate of said flow of water passing through said valve 110 may belinearly proportional to said axial movement of said valve stem 130.

Said valve 110 may thus provide a linear increase in water volume assaid valve stem 130 is threaded out of said valve body 120. Further,said valve 110 may be self-cleaning, as said symmetrical manner of waterflow through said sealing passage 118 and around said plug 137 preventsbuildup of debris or sediment in said valve 110, decreasing the need formaintenance and the likelihood of developing a leak.

Without limiting the invention, FIG. 6 shows a schematic diagram of anexemplary embodiment of circuits of an animal sprayer device 100according to an embodiment of the present invention. In someembodiments, said pressure switch 160 may be capable of opening orclosing a first circuit 172 between said power source 171 and saidmicrocontroller 161. In some embodiments, said pressure switch 160 mayopen said first circuit 172 when said pressure activated piston 116 (seeFIGS. 4 and 5) is not in contact with said pressure switch 160, andclose said first circuit 172 when said pressure activated piston 116 isin contact with said pressure switch 160.

In some embodiments, said power source 171 may be in electroniccommunication with a first transistor switch 164, said first transistorswitch 164 being in electronic communication with said microcontroller161. In some embodiments, said first transistor switch 164 may becapable of opening or closing a second circuit 173 between said powersource 171 and said microcontroller 161. In some embodiments, said firsttransistor switch 164 may close said second circuit 173 upon receiving asignal from said microcontroller 161, said microcontroller 161automatically signaling said first transistor switch 164 to close saidsecond circuit 173 after said microcontroller 161 receives power viasaid first circuit 172, thus bypassing said first circuit 172. In someembodiments, said microcontroller 161 may not signal said firsttransistor switch 164 to open said second circuit 173 after said firstcircuit 172 opens at the end of a spraying period, so that saidmicrocontroller 161 may cause said motor 150 to close said valve 110after said spraying period has ended. In some embodiments, saidmicrocontroller 161 may then signal said first transistor switch 164 toopen said second circuit 173, conserving power from said power source171.

In some embodiments, said microcontroller 161 may continuously monitorthe voltage level from said power source 171 via said first circuit 172(first circuit voltage), and enter a low power mode upon said firstcircuit voltage dropping below a predetermined voltage (e.g., 7.4volts). In some embodiments, upon entering said low power mode, saidmicrocontroller 161 may not signal said first transistor switch 164 toopen said second circuit 173 at the end of a spraying period, butinstead may signal a second transistor switch 165 to cut off power tosaid sensor 180. Thus, said second circuit 173 may remain closed for thepurpose of powering a voltage indicator 170, but said sensor may notdraw any power from said power source 171, conserving battery power. Insome embodiments, said animal sprayer device 100 may be capable ofoperating in low power mode until said first circuit voltage drops belowa minimum voltage (e.g. 4.5 volts).

In some embodiments, if said animal sprayer device 100 is in low powermode, said microcontroller 161 may not close said valve 110 when aspraying period ends, thus conserving power and ensuring that said valve110 is in an open position for the next spraying period. In otherembodiments, said microcontroller 161 may close said valve 110 at theend of a spraying period irrespective of whether said animal sprayerdevice 100 is in said low power mode.

In some embodiments, said microcontroller 161 may exit said low powermode upon said first circuit voltage rising above said predeterminedvoltage.

In some embodiments, said voltage indicator 170 may comprise a lightemitting diode (LED) indicator and be operable to receive power fromsaid microcontroller 161 upon said microcontroller 161 entering said lowpower mode. In some embodiments, upon receiving an activation signalfrom said microcontroller 161, said LED indicator may be operable topulse at a regular interval (e.g. one 0.5 second pulse every fiveseconds), alerting a user that a power level of said power source 171has dropped below said predetermined voltage. In some embodiments, saidLED indicator may continue to pulse at said regular interval until saidmicrocontroller 161 signals said LED indicator to shut down. In someembodiments, said microcontroller 161 may signal said LED indicator toshut down upon said first circuit voltage rising above saidpredetermined voltage.

In some embodiments, said microcontroller 161 may comprise a centralprocessing unit (CPU), said CPU being in electronic communication withsaid pressure switch 160, said first transistor switch 164, said secondtransistor switch 165, said motor 150, said sensor 180, and said voltageindicator 170. In some embodiments, said microcontroller 161 may beoperable to receive power from said power source 171 via a first circuit172 or a second circuit 173, said first circuit 172 being opened orclosed by said pressure switch 160, and said second circuit 173 beingopened or closed by said first transistor switch 164. In someembodiments, said pressure switch 160 may close said first circuit 172upon said water pipe delivering said threshold water pressure to saidvalve 110 during a spraying period, and open said first circuit 172 atthe end of said spraying period.

In some embodiments, upon receiving power from said first circuit 172,said microcontroller 161 may automatically signal said first transistorswitch 164 to close said second circuit 173, bypassing said firstcircuit 172. In such embodiments, said microcontroller 161 maycontinuously monitor a first circuit voltage, and enter a shut-down modeupon said first circuit being opened. In some embodiments, said secondcircuit 173 may thus provide power to said microcontroller 161 during aspraying period as well as after said first circuit 172 is opened at theend of said spraying period. In such embodiments, said microcontroller161 may enter said shut-down mode, wherein said microcontroller 161 maycause said motor 150 to close said valve 110, and then signal said firsttransistor switch 164 to open said second circuit 173. Upon said secondcircuit 173 being opened, power is cut off to said microcontroller 161,said sensor 180, said motor 150, and said voltage indicator 170.

In some embodiments, said microcontroller 161 may be operable to: (1)receive power from said power source 171 via the closing of said firstcircuit 172; (2) transmit power to said first transistor switch 164,closing said second circuit 173; (3) automatically transmit a negativedetection signal to said motor 150 to initially close said valve 110 andconserve water; (4) send a signal to said second transistor switch 165to activate said sensor 180; (5) receive a positive detection signalfrom said sensor 180 upon an animal entering a target area; (6) transmitsaid positive detection signal to said motor 150 to open said valve 110;(7) receive a negative detection signal from said sensor 180 upon saidanimal leaving said target area; (8) transmit said negative detectionsignal to said motor 150 to close said valve 110 and conserve water; (9)monitor a first circuit voltage; (10) upon said first circuit voltagedropping below said predetermined voltage, enter said low power mode andactivate said voltage indicator 170, causing said voltage indicator topulse at a regular interval; (11) upon said first circuit 172 beingopened while not in said low power mode, close said valve 110 and signalsaid first transistor switch 164 to open said second circuit 173,shutting off power to said microcontroller 161; (12) upon said firstcircuit 172 being opened while in said low power mode, either close saidvalve 110 to conserve water or leave said valve 110 open to conservepower, and signal said second transistor switch 165 to cut off power tosaid sensor 180, conserving battery power, and (13) upon said firstcircuit voltage rising above said predetermined voltage, exit said lowpower mode.
